A cylindrical lens or cylinder lens is an optical lens with a cylindrical or semi-cylindrical shape. Like a spherical lens, a cylindrical lens has one curved and one flat side. Unlike a spherical lens, however, cylindrical lenses aren’t fully symmetrical — the orientation of a cylindrical lens affects how it transmits light. Cylindrical lenses is a lens which focuses light into a line instead of a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to intersection of the surface of the lens and a plane tangent to it along the cylinder’s axis. The lens converges or diverges the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to its cylinder’s axis. A toric lens combines the effect of a cylindrical lens with that of an ordinary spherical lens. Optical Cylindrical lenses are designed to focus light into a straight line, rather than to a single point. As the name suggests, the lens surface has a cylindrical shape rather than the usual spherical which allows for one dimensional shaping of light along a line. Cylindrical lenses are typically either plano-concave or plano-convex, designed to expand and focus light respectively, and can be supplied in either diameter or rectangular shape for ease of mounting. VY Optics offers a wide variety of Cylindrical Lenses in a range of substrates or anti-reflection coatings for maximum performance in the Ultraviolet (UV), Visible, or Infrared (IR).

Applications

Cylindrical lens are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lens are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam?shaping to circularize laser outputs. Cylinder Lenses are often used as laser line generators or to adjust the height of images or to correct astigmatism in imaging systems.
